FARMERS HINGE.

To all whom it may concern I Be it known that I, ERWIN W. BAERWALDT,

of Stevens Point, in the county of Portage and State of Wisconsin, have invented certain new and useful Improvements in Hinges; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to new and useful improvements in hinges, and pertains particularly to a device of this nature for use on stock pen and alley gates.

The principal object of the invention is to provide a hinge for use in connectionwith dairy barn equipment which is so constructed that gates, such as stock pen and alley gates, may be swung to either side of a supportingpost and into positions substantially parallel thereto. As such structures are now sometimes. constructed, it is impossible for the gate to'lie parallel when the side of the fence or the like supporting the same, it standing at an angle thereto so that it interferes with the movement of stock along an alley or into a pen.

ments.

It is likewise an important object of this invention to provide a simply constructed hinge which will perform the foregoing functions and which may be largely constructed of four like castings together with the necessary connecting and clamping ele- Obviously byhaving the main parts of identical construction, a relatively inexpensive device can be made.

WVith these general objects in view, the invention consists in the novel features of construction, combination and arrangement of parts which will be hereinafter more particularly described and claimed.

Consequently, various changes may be made in the different parts of the in- Specification of Letters Patent.

any other means may beused for connecting the clamp plates3' ears 6 and 7 in engagement, the pivot ears 8 are spaced apart and disposed one on each side of a longitudinal plane passing through the engaging Likewise when the two members Aand B are assembled, the clamp ears 7 of the same are disposed adjacent each other, and as a result, although the pivot ears 8 of one member are alined horizontally with the pivot ears of the other member, the ears of the first member are adaptedto cooperate with the remote ears of the other member.

In other words, when the centers of each of faces of said ears 6 and 7.

Thus the corresponding pivot ears 8 of the clamp plates 3 anda of the opposite members may be connected by crossed links 5 11; The opposite ends of these links '11 are pivoted to the ears 8 as at 12, the same he'- lng first disposed between the furcations of said ears as is most clearly shown in Fig. 1.

7 By such an arrangement the 'member A is permitted to swingto either side ofthe menr ber B and into parallelism therewith. This feature together with the fact that each of the several clamp plates is of identical construction makes a hinge which willbe not only extremely efficient in operation but which will be capable of being relatively inexpensively manufactured.

I claim: 7 I 1 A hingeincluding a pair-of clamps, one forming a support engaging member and the other a gate post engaging member, each clamp comprising a pair of like post embracing plates, a bifurcated ear extending from each of the plates at one side of a transverse plane through the center thereof, means for clamping the pairs of plates together to engage the gate post and support respectively, and a pair of links, each link being pivoted at one end to the ear of one of the support engaging plates and pivoted at its other end to the car on the diagonally opposite post engaging plate.
